Fiesta radio issue

[Scarletpimpofnel]

2012 Ford Fiesta: I changed the battery in this car and since the radio has a strange issue. It turns on fine BUT you cannot change channel etc, no button presses do anything UNTIL you turn the radio off then on again. After which all buttons work as expected.
What’s going on? Ty

Anyone any ideas? ty

It doesn't surprise me, although I can't offer any specific solution... but sometimes strange things happen when a car is powered down and powered back up; it is the reason that we now never disconnect the power from a car, always backing it up (through the OBD socket) when removing a battery to keep all those ics powered up and memories alive. It may seem unnecessay and over the top, but it potentially saves head scratching/time/cost/embarassment. I learnt my lesson years ago on a Metro that had to be towed to the Rover dealer to have its base engine program reinstalled... merely losing a radio security code or pre-sets can be the least of your problems.

Thanks, yes I agree. When I was a youth disconnecting batteries prevented problems when working on a car... now it seems better to leave it connected and take the risks!
